1983 Map of Dog Mountains

Evidence of human activity in this arid environment is sparse but significant, centered on landmarks such as a lone Landing Strip and named locations like Los Mimbres and Las Palmas. The topographic detail traces the drainage patterns of Horse Canyon and the expansive Deer Flat, providing a clear record of the terrain as it existed when the field checks were completed in the late 1970s. The inclusion of both Spanish and English nomenclature for features such as El Venado and El Aguila reflects the cultural history of this transborder region.
